About RateBase

The platform is free and openly downloadable. The six-state inventory covers investor-owned electric and natural-gas base-rate cases from 2020 forward. Record detail varies with the source material available, and case pages disclose evidence limits rather than filling gaps with estimates. RateBase is not affiliated with a commission, utility, rating agency, or commercial regulatory-data provider.

Corrections must identify the affected case or field, the existing and proposed values, and a direct official source. The repository includes a correction template so published corrections remain visible in version history; its public Issue link will be attached when the launch repository is published.
